- NCT06287775RecruitingPhase 1/Phase 2
Testing a new drug combo for small cell lung cancer
This trial tests adding a new drug, iadademstat, to standard immunotherapy drugs (atezolizumab or durvalumab) for people with small cell lung cancer that responded to initial treatment. The goal is to see if this combination works better at preventing cancer from returning.
La Jolla, CaliforniaAges 18 years+ - NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
La Jolla, CaliforniaAges 18 years+ - NCT06706076RecruitingPhase 1/Phase 2
Experimental pill for lung cancer with EGFR or HER2 changes
This study tests an experimental pill that targets cancer cells with certain gene changes (EGFR or HER2). It may help shrink tumors or slow the cancer's growth in people with advanced non-small cell lung cancer.
La Jolla, CaliforniaAges 18 years+ - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
La Jolla, CaliforniaAges 18 years+ - NCT07431281RecruitingPhase 3
New drug combo for advanced stomach cancer with CLDN18.2
This trial tests a new drug combination for people with advanced stomach cancer that has not been treated before. It looks at two groups: one with PD-L1 (a protein that helps decide if immunotherapy works), and one without. The treatment includes an antibody-drug conjugate (Sonesitatug Vedotin) plus standard chemotherapy, with or without an immunotherapy drug.
La Jolla, CaliforniaAges 18 years+ - NCT06900595RecruitingPhase 2
Cabozantinib with immunotherapy for advanced adrenal cancer
This trial tests adding the targeted drug cabozantinib to the immunotherapy cemiplimab for people with advanced adrenocortical carcinoma that cannot be removed by surgery or has spread. It checks if the combination works better than cabozantinib alone.
La Jolla, CaliforniaAges 12 years+ - NCT06750094RecruitingPhase 3
Study of amivantamab plus FOLFIRI in colorectal cancer
This trial tests adding amivantamab to standard FOLFIRI chemotherapy for people with certain types of colorectal cancer that have already been treated once. It aims to see if this combination works better than another common treatment (cetuximab or bevacizumab plus FOLFIRI).
Tijuana, ArizonaAges 18 years+ - NCT07063745RecruitingPhase 2/Phase 3
Comparing a new drug combo for advanced lung cancer with a specific gene change
This trial tests a new drug called Navlimetostat combined with pembrolizumab and chemotherapy versus a placebo with the same standard treatments. It is for people with metastatic non-small cell lung cancer that has a specific missing gene (MTAP deletion) and who have not had prior treatment for their advanced disease.
Tijuana, Estado de Baja CaliforniaAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 3
Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Tijuana, Estado de Baja CaliforniaAges 18 years+ - NCT07361497RecruitingPhase 3
New Drug vs Standard Drug After Chemoradiation for Stage 3 Lung Cancer
This study tests a new drug, pumitamig, against an older drug, durvalumab, for people with stage 3 non-small cell lung cancer that cannot be removed by surgery and has not progressed after chemotherapy and radiation. The goal is to see which drug works better to keep the cancer from growing.
Tijuana, Estado de Baja CaliforniaAges 18 years+ - NCT05855200RecruitingPhase 3
Dostarlimab around surgery for certain untreated colon cancers
This trial studies dostarlimab given around the time of colon cancer surgery for people with untreated, resectable (operable) stage T4N0 or stage III colon cancer that has specific tumor markers. It may help shrink or eliminate the cancer before or after surgery by boosting the immune response.
Tijuana, ArizonaAges 18 years+ - NCT04929223RecruitingPhase 1
Targeted drug study for metastatic colon or rectal cancer
This Phase 1 study tests targeted cancer treatments in people with metastatic colorectal cancer, using genetic “biomarker” results to match you to the right treatment group. It focuses first on safety, and also looks for early signs the treatment may work in specific tumor subgroups.
Encinitas, CaliforniaAges 18 years+ - NCT06710067Recruiting
Urine chemicals for diagnosing disease
This study looks at chemicals in urine to help find new ways to diagnose diseases. You give one urine sample and answer a few questions—no treatment or long-term follow-up needed.

Blood test study for people at risk for or with liver cancer
This trial tests a new blood test to help detect liver cancer (HCC) or confirm it’s not present in people with cirrhosis who are being monitored. It may help improve how doctors screen for liver cancer and decide who needs further imaging or treatment.

What taking part in a cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
